Soyuz TM-3 was the fourth manned spacecraft to visit the Soviet space stationMir. It was launched in July 1987, during the long duration expedition Mir EO-2, and acted as a lifeboat for the second segment of that expedition. There were three people aboard the spacecraft at launch, including the two man crew of the week-long mission Mir EP-1, consisting of Soviet cosmonaut Alexander Viktorenko and SyrianMuhammed Faris. Faris was the first Syrian to travel to space, and as of November 2010, the only one. The third cosmonaut launched was Aleksandr Aleksandrov, who would replace one of the long duration crew members Aleksandr Laveykin of Mir EO-2. Laveykin had been diagnosed by ground-based doctors to have minor heart problems, so he returned to Earth with the EP-1 crew in Soyuz TM-2.[2]
